An additional object of theinvention is to provide an implement of the character described including series of soil working plows or shovels, mechanism for operating them as an incident to the movement of the implement, means for adjusting them to work the soil at varying depths as desired, and leveling and pulverizing devices in- 'i cluded in the implement for leveling and pulverizing the' soil after it has been worked by the plows or shovels in preparation for planting.

'A Afurther object of the invention is to provide an improved agricultural implement comprising a power propelled frame, tractor wheels for supporting and carrying the frame, a revoluble shaft supported by the frame, a'series of soil pulverizing spiral knives or cutter blades supported by the revoluble shaft, mechanism for revolving the shaft and 1thereby the knives as an incident to the travel of the implement, and a device for adjusting the knives or blades to operate into the soil atY varying selected depths.

Another object of the invention is to provide an agricultural implement comprising a power driven truck or frame,.revoluble series of shovels orplows supported by the truck or frame, mechanism for revolving the series as an incident to the` travel of the implement, a series of soil pulverizing knives or blades extending transversely of the implement, mechanism for operating the knives or blades to work the soil after the soil has been worked by the4 plows or shovels, and mechanism foradjusting the plows or shovels andthe knives` or blades relative to work into the soil at varying relative depths, as desired.

Another object of the invention is to provide an implement constructed and embodying the'mechanisms last mentioned, in combination with planting mechanism carried by the implement for planting in the soil after-the soil has been acted upon by the mechanisms mentioned, and a corrugated roller attachment for crushing-.and pulverizing the soil in the rear of the planting mechani'sm.

`An additional object of the invention is to provide an agricultural implement embodying means for leveling and laying transversely thereof any vegetation in the path ofthe implement, disk cutters for cutting the vegetation, and cutting the soil into elongated parallel strips preparatory for the action of the plows of the soil working mechanism, and soil working mechanism for working the soil after the vegetation has been cut to prepare the soil properly for planting.

Various other objects will appear from the following description, reference being made to the accompanying drawings illustrating one embodiment 'of the invention, in which- Figure 1 isa side elevation o an agricultural implement-,constructed in accordance with the present invention.

Fig. 2 is a plan view of the implement;

Fig. 3 is a forward end elevation.

supported by tractor wheels' 3, the axles ofwhich are inclosed within theusual housings 4 and are driven from the engine by any of the ordinary well known gearings inclosed Within a housing 5. The forward end of the frame is equipped with a steering device 6 comprising a wheel operating upon the ground and controlled by a. steering post and wheel 7 in a well understood manner. A depending frame 8 is supported in the frame 2 near the forward end thereof and in said frame are mounted two rollers or wheels 9, one being near each side of the implement and both of them at a slight distance above the ground. A chain 10 actuated by theengine shaft 11 passes around a sprocket wheel in connection with one of the rollers 9, so that the rollerI will be revolved when the engine is running. A belt 12,is operatively supported by the rollers 9 and carries a series ofcurved arms 13, which when the belt ismoving will engage with the vegetation in the path of the implement and lay the vegetation transversely of the implement in position depressed upon the ground by the lower horizontal frame part 14 in position to be cut by the cutters, which' also serve the purpose of cutting the soil into j elongated parallel strips preparatory for the plow and pulverizing mechanism, as hereinafter explained.

The frame 8- is vertically adjustable and the adjusting devices therefor include two racks 15 att-ached to the respective ends of the frame 8 and engaged by pinions 16 upon a transverse shaft 17.. The shaft 17 is revoluble in bearings upon the frame 2 and 4with the pinions 16 to prevent accidental turning of the shaft. As shown the ratchets 19 are pivoted to theframe 2 and may be moved manually tol engage or release the pinions. By raising the frame 8 to permit the chain 10 to become slack, the chain may be disengaged from one of the sprockets to enable the implement to travel without operating the rake devices consisting of the belt 12 and thearms 13.

'Twoarms 20 are pivoted upon the axle shafts of the tractor wheels, one at each side of the implement,'and provided with vertical extensions 21. Each vertical extension is between two alined abutments in the form ofadjustable screw shafts 22. Thescrew shafts 22 are mounted in the frames attachedto frame 2 and each comprisingvertical arms 23,50 that byturning theshafts 22 thearms 20 will be raised or lowered as a result Yof their engagement with theshafts 22, as described. The forward en'ds of thearms 20 support ahorizontal shaft 24 to which a series of cutters 25Y are attached. As shown, thecutters 25 are in the form of concave disks, but the form of these cutters may be varied. By operating the -adjustingshafts 22 thecutters 25 may be retained, vSo that they will cut into the ground and, in addition to cutting the vegetation, they will demark or cut the surface of the ground in elongated parallel strips preparatory for the working action of the plows o r shovels.

The axle shafts also pivotally support two arms 26, one at each side of the implement, provided withextensions 27 at their forward ends engaging betweenY the adjusting shafts 28 mounted in the frames 23'.- rlhe shafts 28 are Aprovided. with manually engageable wheels orhandles 29, whereby the shafts 28 may be turned as required to raise or lower the rearward portion of' the arms 26. Ashaft 30 is journaled'in bearings near the rearward extremities of the arms 26, and

said shaft supports spiral series of rows of radial arms 31. vOne series of rows Vof thearms 31 is preferably somewhat longer than the other. series of rows of said arms. Each arm supports a shovel 'orplow 32 consisting nground when the implement is .in motion.

As will be' clearly understood by reference to Fig. 1, each alternate row of plows or shovels is longer or shorter as the case may be than thetwo adjacent rows, so that one series of rows of the Vshovels or plows will work deeper into the ground that the other series. thus thoroughly breakingl and slicing the ground into smaller fragments prei paratory for further working by the cuttingknives. As previously mentioned, the ground is cut into' strips by thecutters 25 and since theplowsor shovels 32 work at different depths, there is slight resistance to the breaking up of the ground by these devices. In order that the ground may be thoroughly aerated as 'a result of the working of the plows, the latter are provided withholes 33 for the passage of the air and the percolation .of the smaller fragments of the ground as the series of plows revolve. As will be understood by reference to Figs. 5, 6 and 7, the plows are dished as shown at 34'mLidWay between the side edges thereof, in order'to provide spaces for engagement ofl the arms 31 with the plows and to prevent the soil from adhering thereto. The dished portions 34 extend to and merge into the `pointed extremities.

large gears 36 attached to the tractor wheels l 3, so that when the implement moves forwardly the shaft is revolved rearwardly, thus causing the plows or shovels to work into the ground during the forward movement of the implement.

Theshaft 30 supports twosprocket wheels 37, andchains 38 are operatively connected to thesprocket wheels 37 and tosprocket wheels 39 attached to ashaft 40. r)theshaft 40 is journaled in bearings in arms 41 eX- tending obliquely downwardly andl rear wardly from detachable supports 42 connected to the frame 2. The arms 41 are pivoted upon the supports 42 and are provided with extensions 43 engaging between the screw shafts 44 revolubly mounted in frames 45 attached to the frame 2. rfhe shafts 44 are provided with handles orwheels 46, whereby said shafts may be turned to actuate the arms 41, as required to raise or lower the rear portions thereof.The'shaft 40 supports a series of radial arms 47 adjacent to each of the side members of the frame 2, and each pair of said arms supports a transversely mounted spiral knife orblade 48 adapted to workinto the ground i and to complete the pulverization thereof,

where such result was' not completely. effected by the devices previously mentioned. By manipulation of the shafts 44 the knives orblades 48 may bev raised or lowered to work into the ground at any desired depth. The series of knives are revolved in opposition to the ground, so that when the implement travels forwardly the series of knives are revolved in a reverse direction, thus completely pulverizing the ground and completing the preparation thereof for planting.

rEhe plantingmechanism includes ahopper 49 supported upon the frame 2 rearwardly from the pulverizing and ground working mechanism, and the seed are conv veyed into the pulverized and prepared groundV from thehopper 49 through the usual passages orchutes 50. The planting mechanism is not illustrated in detail for it is intended that any of the well known planting mechanisms now in use may be applied to the implement and operated in the usual manner. The illustration of the planting'mechanism therefore is Vmerely conventional and diagrammatic for the purpose of illustrating the location thereof relative to the other parts of the implement.

It is desirable in some instances to oper'- Y ate a rolle'l` over the ground after it has been planted, and I have included in'the implement illustrated a device for effecting this inal operation in the series of operations involvedin plantmg. Ashillustrated to travel over a road,

there are twoarms 51 pivotally supported by the frame 2 and constituting a journal for thel shaft of aroller 52. The surface of theroller 52 is illustrated as of a corrugated con'iguration in order to leave the surface ofI the ground in ridged or drill form -and to complete the crushing and pulverization of the ground upon the seed which have been planted, and to press the prepared quantity of the soil upon the seed. It .is obvious, however, that the roller may be otherwise formed and do not restrict myself to any particular design for the' roller.

rlhe arms 51 are removably supportedv upon pivots 53 as the arms 41 are removable upon the pivots42. Thus, when it is desired the roller and the cutting attachmentmay be detached from the frame and the frame may be converted into a truck by placing thereunder any of the usual truck frames in common use. Also, the remaining mechanisms may be moved to and retained in-idle positions while the iinplement is being transported over the road. As before mentioned, the belt appliance 12 may be raised to idle position by operation of the cranks 18. Thecutters 25 may also be raised to and supported in idle position by adjustment of theabutment shafts 22.' Likewise, the plow and' shovel mechanism may be raised to and supported in idle position out of the ground and out of contact with the road surface-by manipulation of the shafts 28'.

An implement embodying the various and several devices described for working and treating the ground in successive stages of its treatment is highly eiiicient and comparatively rapid in operation, and not only cuts the vegetation into. proper length to be turned under, but also thoroughly works and aerates the ground by allowing it while in the mulched condition and raised position to be thoroughly permeated by the atmosphere; and thereafter pulverizes and levels the ground after the planting has been completed. ln addition to levelingthe ground the' roller also presses the soil upon the seed and thus completes the final one of the series of steps or stages of treatment required in order to place the ground in best condition for the growth of the crop.

i am aware that there may be various alterations in the construction and arrangement of the parts and mechanisms'and that the different devices may be located in other relative positions than those illustrated. I

Vdo not restrict myself to the Aspecific arrangement of the various devices, nor to the simultaneous use of allof them, for the reasonthatl in. some instances itmay not be necesoccasions the roller is not required. These and other var1at1ons\are w1th1n contemplation.
